论文摘要
在本文中，我们研究了窗帘涂料配置中的动态润湿。两阶段Navier-Stokes方程通过自适应笛卡尔网格上的流体量方法求解。我们介绍了Navier边界条件，以使解决方案处于三个点处并删除由以细胞为中心的接口对流引起的隐式数值滑移。我们使用恒定的接触角来描述动态接触线。管理方程的分辨率使我们能够预测发生润湿失败的底物速度。将模型预测与先前的计算和实验观察结果进行了比较。
In this paper we investigate dynamic wetting in the curtain coating configuration. The two-phase Navier-Stokes equations are solved by a Volume-of-Fluid method on an adaptive Cartesian mesh. We introduce the Navier boundary condition to regularize the solution at the triple point and remove the implicit numerical slip induced by the cell-centered interface advection. We use a constant contact angle to describe the dynamic contact line. The resolution of the governing equations allows us to predict the substrate velocity at which wetting failure occurs. The model predictions are compared with prior computations and experimental observations.
